I think I may have blown out my Torque Converter yesterday while downshifting on a big hill. I'm looking to go aftermarket and I was wondering who makes a good torque converter with towing specifically in mind, not racing. Thanks for the input.

We have had 3 PowerStokes with BTS tranmissions in them. Two of the trans are/were 4R100s behind the 7.3s and one is a 5R100 in my 6.0. Great for pulling racing whatever!!! These trucks have Percision Industries converters and they are a great product. Call up Brian's Truck Shop and they will hook you up with a converter or built trans. You could always call them up after you go with some other brands of trans/converters I can't tell you how many "other brands" of transmissions/converters I have seen getting pulled out of customers trucks at BTS. I am not on a soap box just speaking from what I have seen and heard.

After what I've read on here and everything I've heard, I'd go suncoast, and I plan to do so at some point (when funds allow)

With just a tuner, I broke the original TC with only 40K miles on the truck, now 3k miles later I think this one is going again because the dealer didn't replace the trans cooler when they put the new tranny in...

I didn't replace trans cooler OR torque convertor when I replaced my tranny 75K miles ago BUT I didn't have a catastrophic failure either. Just 40K miles of a predator and it was tranny and 3 sets of head gaskets.
